Lawmakers will vote Wednesday on a measure that would protect military service members who disagree with homosexuality on religious or moral grounds.

If approved, the measure authored by Rep. Todd Akin, R-Mo., would be attached to the 2013 defense funding bill.

Akin told CBN News there currently aren't any laws to protect the conscience rights of military chaplains since the repeal of "Don't Ask, Don't Tell" last year.

The measure would not only protect military chaplains but all service members who object to the homosexual lifestyle.

"There's pressure on them in terms of advancement. If you don't do what you're supposed to do then you won't get a promotion," Akin said.

"You won't be allowed to do this, or you get a bad fitness report," he continued. "So this is one of those things so that people can be faithful to the group that they came from and allows them sense of an umbrella protection."

The measure will be voted on today as part of next year's defense funding bill.
